  • Patent number: 7747145
    Abstract: An optical disk for recording stereoscopic videos and high-quality video signals and a system for reproducing the videos and signals from the optical disk are made compatible with the conventional video reproducing system. A reproducing device which is used for reproducing stereoscopic videos and high-quality videos obtains stereoscopic video or high-quality videos by reproducing both first and second interleaved blocks on the optical disk in which first and second video signals are alternately recorded on the left and right sides by dividing the first and second video signals into frame groups of one GOP or more and a reproducing device which is not used for reproducing the stereoscopic videos and high-quality videos obtains ordinary videos by only reproducing either the first or second interleaved block by jumping tracks.

  • Publication number: 20090193802
    Abstract: A control method for a hydraulic type continuously variable transmission for suppressing a harmful effect due to the reacceleration just after deceleration of a vehicle. In a hydraulic type continuously variable transmission, the operation of a shifting actuator is stopped to suspend the shift control (S7) when a throttle valve is rapidly opened just after fully closed (S4: Yes) and an engine speed NE [rpm] is being rapidly increased (S6: Yes). Accordingly, even when the actual engine speed NE becomes much greater than a target engine speed T_NE during reacceleration just after deceleration of a vehicle, unexpected shift control (upshifting) can be prevented, so that more desirable torque can be produced.

  • Patent number: 7550556
    Abstract: The present invention is to prevent the rapid viscosity rise generated at the time of dissolving or dispersing in a solvent a polymer obtained by reacting a material polymer having an acidic functional group and a hydroxyl group in the principal chain part with an isocyanate compound, in particular, a photo-curing polymer obtained by reaction with a radical polymerizable group-containing isocyanate compound. A highly stable polymer can be obtained by reacting a material polymer having a principal chain including at least a component unit having an acidic functional group and a component unit having a hydroxyl group with an isocyanate compound, and further reacting the same with an alcohol. Moreover, by producing a material polymer using a non-nitrile azo-based or peroxide-based polymerization initiator and/or introducing an isocyanate compound using a polymerization inhibitor selected from the compounds represented by the above-mentioned formulae (10) and (16), the transparency can be improved.

  • Publication number: 20090087169
    Abstract: A recording apparatus is for a DVD on which a TS-VOB, and pieces of playback path information each showing a playback path of the TS-VOB are recorded. When extended control with various contents can be executed by an apparatus at the time of playback, an extended attribute section in which extended control is valid is specified in accordance with the contents of the extended control. When an extended attribute section is to be uniformly specified for playback paths of the TS-VOB, a section marker for specifying a location of the extended attribute section of the TS-VOB is generated in VOB information. When an extended attribute section is to be individually specified for one playback path, a section marker specifying a location of the extended attribute section of the playback path is generated in PGC information. The generated VOB information and PGC information are written to the DVD.
